Silver Award – U.S. 6 Reconstruction, Noble County, Ind.
Contractor: Primco Inc.*
Owner: Indiana Department of Transportation
Engineer: Beam, Longest & Neff LLC
Shortly after the construction of a new bridge by Norfolk Southern Railroad in Noble County, Ind., Primco was given a 90 calendar day road closure to connect 3,600 feet of 9.5 in. PCCP roadway to the existing road tie-ins and the new bridge.
This was an alternate bid job with concrete winning out after the consideration of life-cycle costs vs. first costs. The concrete pavement was completed in two 16 ft. passes with a safety edge. Robotic stations were set up at 250 ft. intervals to improve the accuracy of paving and to help impart a smooth ride.
The pavement was finished with a 10 ft. straight edge to double check smoothness with 5 ft. overlapping passes. Additional steps were taken to check the edge slump and ensure the best quality pavement. At total of 12,871 SY of concrete was placed at a cost of just over $517,000. The contractor earned more than $85,000 in incentive pay.
